Fullscreen Activity in Android?

Question

How do I make an activity full screen? I mean without the notification bar. Any ideas?

Answer 1

In AndroidManifest.xml file:

Or in Java code:

protected void onCreate(Bundle savedInstanceState){
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
